Figure 9. Quantification of immunohistochemical staining of oral myofibroblasts using an anti-Ki67 antibody.
A robust increase in Ki67-positive cells was observed following treatment with S-nitrosoglutathione (GSNO; 0.5 mM) for 90 and 180 min. Values denote the means ± standard deviations. * denotes a significant difference (P<0.05) compared with untreated cells.
